2011-11-07constexpr: static data members declared constexpr are required to have anRichard Smith
initializer; all other constexpr variables are merely required to be initialized. In particular, a user-provided constexpr default constructor can be used for such initialization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144028 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-07When we notice that a member function is defined with "= delete" or "=Douglas Gregor
default", make a note of which is used when creating the initial declaration. Previously, we would wait until later to handle default/delete as a definition, but this is too late: when adding the declaration, we already treated the declaration as "user-provided" when in fact it was merely "user-declared". Fixes PR10861 and PR10442, along with a bunch of FIXMEs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144011 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-07Drastically simplify the mapping from the declaration corresponding toDouglas Gregor
the injected-class-name of a class (or class template) to the declaration that results from substituting the given template arguments. Previously, we would actually perform a substitution into the injected-class-name type and then retrieve the resulting declaration. However, in certain, rare circumstances involving deeply-nested member templates, we would get the wrong substitution arguments. This new approach just matches up the declaration with a declaration that's part of the current context (or one of its parents), which will either be an instantiation (during template instantiation) or the declaration itself (during the definition of the template). This is both more efficient (we're avoiding a substitution) and more correct (we can't get the template arguments wrong in the member-template case). Fixes <rdar://problem/9676205>. Reinstated, now that we have the fix in r143967. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143968 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-07Rip out one of the features I added for the driver-include-management.Chandler Carruth
We don't actually need a separate flag for non-sysrooted paths as the driver has to manage the sysroot anyways. The driver is not infrequently adding paths to the header search based on their existence on the filesystem. For that, it has to add the sysroot anyways, we should pass it on down to CC1 already joined. More importantly, the driver cannot in all cases distinguish between sysrooted paths and paths that are relative to the Clang binary's installation directory. Essentially, we always need to ignore the system root for these internal header search options. It turns out in most of the places we were already providing the system root in the driver, and then another one in CC1 so this fixes several bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143917 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Throw the switch and move all Linux header search over to the GCCChandler Carruth
detection system that is providing the library paths and crt object files. This, modulo any bugs that need to be shaken out, resolves numerous bugs with how we handle header paths. Here are a few that I know of: - We no longer need to enumerate all GCC versions searched. - OpenSUSE searched GCC versions in the wrong order. - There were typos when selecting various patterns, etc. - We aren't stating quite some many directories now. - SysRoot didn't always work in a reasonable way. I'm working on tests for this, but the tests are making me and Lit sad. The real testing for this type of driver change is to try it out on various distributions. I'll hit the common ones right away, and start more thorough testing tomorrow after some sleep. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143874 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Change the AST representation of operations on Objective-CJohn McCall
property references to use a new PseudoObjectExpr expression which pairs a syntactic form of the expression with a set of semantic expressions implementing it. This should significantly reduce the complexity required elsewhere in the compiler to deal with these kinds of expressions (e.g. IR generation's special l-value kind, the static analyzer's Message abstraction), at the lower cost of specifically dealing with the odd AST structure of these expressions. It should also greatly simplify efforts to implement similar language features in the future, most notably Managed C++'s properties and indexed properties. Most of the effort here is in dealing with the various clients of the AST. I've gone ahead and simplified the ObjC rewriter's use of properties; other clients, like IR-gen and the static analyzer, have all the old complexity *and* all the new complexity, at least temporarily. Many thanks to Ted for writing and advising on the necessary changes to the static analyzer. I've xfailed a small diagnostics regression in the static analyzer at Ted's request. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143867 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Revert r143864, as the problem I was actually looking at can be solvedChandler Carruth
a better way. The more I think about it the more worried I am that this hammer is simply too large. We should only be reaching out to the filesystem when doing interesting "detection" things, not gratuitously. Original commit message: Start pruning down the set of flags passed to CC1 for header search. This cleans up the CC1 invocations, and reduces the overhead there. We're still hammering the filesystem looking for the C++ standard libraries though. The only reservation I have about this policy is the case of virtualized files inside of CC1, but it's not clear what the best way to solve that is. The Driver consistently queries the actual filesystem to make its decisions. Changing that would be a very large undertaking. It might be worthwhile, but it's not an immediate goal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143865 91177308-0d34-0410-b5e6-96231b3b80d8
